I have been dealing with this issue for about a week now and hoping its not tune related. (got the base tune back in February) my 2006 eclipse gs will idle so low after being driven that it almost dies... it always comes out of it after doing it 4 or 5 times. Runs perfect just randomly idles extremely low whether clutch is pushed in or just in neutral. No check engine lights. Any ideas? Thanks

Often, a low idle can be related to the idle learning. You can connect and in the diagnostics menu select reset learned. If you check the factory service manual, it gives the procedure for the factory idle re-learn. If you could list your mods, it is sometimes easier to identify if any of them may be having an impact.
